Similarity of the Boson Peaks in Disordered Systems to the van Hove Singularities in Regular Crystals
I. A. Gospodarev, V. I. Grishaev, O. V. Kotlyar +6
Phonon spectra of solid substitutional solutions with finite concentrations of impurities were analyzed on the microscopic level. The local phonon densities of impurity atoms were…
